Background
The twin screw extruder is a common plastics masterbatch manufacturing apparatus. Continuous uniform blanking is the basis for ensuring smooth production. The traditional blanking device for the double-screw extruder is only a pure feed hopper. Because the raw materials for manufacturing the plastic master batch are filled in granules and other auxiliary materials are added, the raw materials are easy to accumulate in the feed hopper and can form blockage in severe cases. Once the blockage is formed, the machine needs to be stopped for cleaning, the production efficiency is extremely low, and the requirement of modern production is completely not met. Later, many manufacturers began to address or prevent the build-up of material within the hopper by various means, generally classified into two categories. Firstly, make the material become loose state in the feeder hopper through the stirring mode, prevent effectively that the material from forming the jam, but so the material is too loose, and unloading pressure is not enough, hardly reaches the reinforced requirement when twin-screw extruder production, consequently adopts seldom. Secondly, the material is pressed in through the pressing mechanism, the problem of blockage is solved, the blanking pressure is also sufficient, but the existing pressing mechanism has the great defect that the material is accumulated at the peripheral top of the pressing mechanism, when the pressing mechanism retracts, the material is difficult to quickly and intensively enter the bottom of the pressing mechanism, the pressing mechanism is often empty, continuous uniform blanking cannot be realized, and equipment is difficult to continuously and effectively output qualified products. Consequently, design a section can be when swager constructs the back that contracts, and quick high efficiency fills the swager constructs the below with the material to effectively prevent that swager constructs and empty, can effectively ensure that the material continuation carries out the unloader of the double screw extruder of even unloading and be the utility model discloses a research purpose.
